Interaction of Electrons with Atoms in Ground and Excited States; Potential of Interaction, Momentum Transfer Cross‐Sections

In this paper the potential of the electron-atom interaction was presented which may be useful both in the case of the ground state of an atom with one optical electron and in the case of the excited state of any atom, and which is given by expressions suitable for operational use. The presented potential is used in calculating the transport cross sections for the elastic electron scattering on the atoms of H, Li and Na respectively, in the ground and excited states.
